Windows 11 Infinite Black Screen Loop After Failed Windows 10 Reset

Hi everyone,

I am reaching out for assistance due to a challenging issue with my Windows 11 system, which is currently stuck in an infinite loop of a black screen with spinning circles. This issue arose unexpectedly after an attempt to reset my Windows 10 system on a separate disk failed, suggesting that the reset operation inadvertently impacted my primary Windows 11 system.

Here's a detailed breakdown of the events leading to the current problem:

• My setup includes two hard drives: Disk A with Windows 11 (my primary system) and Disk B with Windows 10.
  
• I encountered a DLL file missing error on Windows 10 (Disk B) and after unsuccessful attempts to fix it through runtime library installations and the SFC command, I decided to reset the Windows 10 system via the settings, choosing to reset only the system disk to avoid affecting other drives. Unfortunately, the reset failed.
  
• Subsequently, attempting to boot into Windows 11 on Disk A resulted in a blue screen error related to the NTFS file system on the first attempt, followed by an automatic repair on the second attempt. After the repair, the system now persistently shows a black screen with spinning circles, unable to proceed to the login screen.
  

Additional details and steps taken:

• Through the Troubleshoot options, I can access CMD and open Notepad, confirming that the disks are accessible.
  
• I have created a Windows installation USB drive and attempted its repair functions without success.
  
• My setup involves two monitors, with the BIOS and system defaulting to monitor A, but Windows set to display only on monitor B. Post-issue, the system disconnects from monitor A and attempts to load on monitor B, indicating partial loading of Windows configurations.
  

It seems the reset attempt on Windows 10 has unexpectedly affected the Windows 11 system on the other disk. Given the steps I've already taken without success, I am seeking your expert advice on how to resolve this infinite loading issue and recover access to my Windows 11 system.

Any suggestions, guidance, or recommended steps to troubleshoot and resolve this issue would be greatly appreciated. Thank you very much for your time and assistance.

 

Black Screen after Log on

Laptop or Desktop (Very important) Windows 10 build 14.586 has a very annoying BUG: That causes Black Screen after login:
To date there is no cure until Microsoft send Update to fix the problem: OK here goes: When you Login and the Screen Goes Black ==>
Go to your Function Keys for Screen Brightness Chose to Lighten the Screen (This will make the screen Bright) so that you can view it.
The BUG is that they reversed (via Software) what the Brightness button does -- So it is currently reversed -- "Lighten" makes it Dark -- "Darken" makes it Bright ==> Go figure Microsoft screw the pooch on this one. . . .

This is for LAPTOP -- I have never seen this on Desktops but they are fixed rather than adjustable
